Cyclization/cleavage strategies offer superior solid-phase synthesis of heterocycles, yielding high-purity products. These traceless methods leverage solid-phase benefits for efficient preparation of pharmacologically important compounds.

Area of Science:

  • Organic Chemistry
  • Synthetic Chemistry
  • Medicinal Chemistry

Background:

  • Solid-phase synthesis offers practical advantages for preparing complex molecules.
  • Traditional methods for heterocycle synthesis can be challenging in terms of product purity and efficiency.
  • Cyclization/cleavage (C/C) or cyclorelease strategies have emerged as powerful alternatives.

Purpose of the Study:

  • To highlight the superiority of cyclization/cleavage (C/C) or cyclorelease strategies for solid-phase preparation of heterocycles.
  • To emphasize the advantages of C/C approaches in leveraging solid-phase synthesis benefits.
  • To showcase the high purity and traceless nature of products obtained via cyclorelease.

Main Methods:

  • Utilizing cyclization/cleavage (C/C) or cyclorelease strategies for solid-phase synthesis.

  • Employing various bond-forming reactions (C-N, C-O, S-S, C-C) in the final cyclorelease step.
  • Focusing on the preparation of pharmacologically important heterocycles.

    • Main Results:

    • C/C strategies provide significant advantages for solid-phase synthesis.
    • Cyclorelease approaches yield final products with generally high purity.
    • These strategies are "traceless", with the cleaved moiety incorporated into the heterocycle.

    Conclusions:

    • Cyclization/cleavage (C/C) or cyclorelease strategies are superior for the solid-phase preparation of diverse heterocycles.
    • These methods maximize the benefits of solid-phase synthesis, ensuring high product purity and efficiency.
    • Over thirty years, numerous successful applications of these strategies have been reported for various heterocycle classes.
